Clarifier

Clarifier helps with water that looks hazy but tests fine. It binds fine particles into bigger clumps your filter can trap. It works best with a clean filter and a pump that runs enough hours.

Use it as a small boost, not a cure. If the haze comes from low chlorine, high pH, or a worn filter, fix those first. Too much clarifier can make water cloudier. After use, clean your cartridge or backwash the filter, since it will be full of trapped debris.
